# 1Password Developer Workflows This skill covers the 1Password developer toolchain: SSH key management via the SSH agent, secrets injection via Environments, and the `op` CLI. ## Quick Reference | Tool | Purpose | |---|---| | 1Password Desktop App | SSH agent, key imports, environment management | | `op` CLI (stable) | Item management, secret references, `op run`, `op inject` | | `op` CLI (beta) | Adds `op run --environment` and `op environment read` | | SSH Agent | Serves keys from 1Password vaults to SSH/Git clients | | Environments | Store and inject env vars at runtime without plaintext on disk | ## SSH Key Management ### Supported key types 1Password supports only these SSH key types: - **Ed25519** (recommended, fastest, most secure) - **RSA**: 2048, 3072, and 4096-bit only Not supported: ECDSA, DSA, RSA keys larger than 4096-bit (e.g., 6096-bit), PuTTYgen `.ppk` format. Check a key's type and size before importing: ```bash ssh-keygen -lf ~/.ssh/your_key # Output: 256 SHA256:abc... user@host (ED25519) # Output: 4096 SHA256:xyz... user@host (RSA) ``` ### Importing SSH keys The CLI **cannot** import existing SSH keys. This is a desktop-app-only operation. From the official docs: "To import an existing SSH key, use the 1Password desktop app." To import via the desktop app: 1. Navigate to the target vault in the sidebar 2. Select **New Item > SSH Key** 3. Select **Add Private Key > Import a Key File** 4. Navigate to the key file and import 5. If the key has a p
